It’s been five years since the launch of the Oral-B iO series, which set out to provide a gentle, yet powerful, clean. It did this by incorporating micro vibrations, while Oral-B electric toothbrushes had previously relied solely on oscillating action and a pulsing effect, which some people found too harsh.
Now, there are nine models in the iOS series, and the iO9 is one of the more premium options, offering top-of-the-line features seen on the more expensive iO10. These include AI brushing recognition technology, which is a very fancy way of saying that the brush is app-enabled and should – in theory – help you become a better brusher. There are also seven cleaning modes on the iO9, which is more than a lot of the Oral-B line-up.
